For the match of terms to the parts of the image they describe:
- Top left - Object providing force
- Bottom left - Gravity
- Top right - Balanced force
- 2nd right - Unbalanced force
- 3rd right - Object receiving force
- 2nd to the bottom - Friction
What described these forces?
Object receiving force: This term would apply to the boy being pushed, as it is the object that is receiving the force exerted by the robot.
Unbalanced force: This term would apply to the force arrow coming from the robot pushing the boy. If the force is unbalanced, it means there's more force being applied in one direction than in others, causing movement or a change in movement.
Gravity: This force acts downwards towards the earth's center, so it would apply to the downward arrow.
Object providing force: This term would refer to the robot that is applying the force to the boy.
Friction: Friction is a force that opposes motion, it is the force opposing the push, often represented by an arrow pointing opposite to the direction of movement, likely at the contact point between the boy and the surface he's on.
Balanced force: The term would apply to a situation in the image where the forces are balanced (no movement or constant movement).
